Yes.  If there's interest, I'll make it available pre-built.  Glut works
with no problems, as far as I can tell.  (My research project depends on
it.)

No.  It's due to "WIN32" instead of "_WIN32" in (one of?) the glut .h
file(s). Change that (I think in two places) and it will compile.

   s/WIN32/_WIN32/g

You need to make yourself a makefile, too, but it can be dirt simple.

Oh, I used the msvc GL header files.  Don't know about the mesa ones.

The sgi header files (for win32) work too, I believe.  I think that's
where the ones in the X tarball came from.  (off the top of my
head...could be wrong.)

But unless you are hacking on mesa (good for you if you are), why not use
the opengl32.dll and glu32.dll that comes with mswindows?  They will
automatically use the optimized drivers for your graphics card.  Does mesa
in win32 now use the drivers to get good acceleration?

Don't know about mesa.  The reason I use win32 is so that OpenGL uses the
vendor-provided drivers for my accelerated graphics card.  Otherwise, I'd
probably run my project in linux.


HTH,
